that shall comprise means whereby the,

' spraying operation may be. started and stopped quickly and the fluidprevented from dripping or spreading to parts other than those to whichit is to be applied.

Another object of my invention is to provide means for so cleaning thevarious passages of a sprayer as to prevent a spraying fluid such as-aliquid from accumulating and drying therein when the sprayer isinactive.

Another object of my invention is to provide distributing means, for asprayer, that shall so control the spraying fluid or liquid as to permitit to be directed. and placed uniformly, over an area of selectivelypredeing mist, splashing or other disturbances usually attending theplacing of an object ,in the path of a rapidly flowing fluid spraystream. I

Another object of my invention is to pro vide mechanical means forattachment adjacent a circular fluid orifice for uniformly directingthefluid stream without splitting the same. v

Another object of my invention is to provide a sprayer. havingcorrelated fluid or liquid and compressed air passages, in which theliquid is prevented from flowing into the air' passages by the movementor certain positioning of, the sprayer when the air is shut off.

In Patent No. 1,231,222 issued to me June 26, 1917 a spraying machine isdisclosed embodying a sprayer, somewhat similar to the sprayerhereinafter described; for distributing a relatively-heavy liquidmixture. While my invention comprehends a broad field of termined shapewithout causing the rebound- I L use, reference to the above patentmaybe had for a clear understanding of a specific use for which it isparticularly adapted.

respectively, of another modified form of distributing member for thesprayer; and Figs. 14 and 15 are side and front elevational views,respectively, of another modified form of distributing member for thesprayer.

The sprayer comprises. in general, a body member 1 having a portion2disposed in J right-angular relation thereto, a nozzle 0 adjacent oneend of the portion 2, a liquidcontrol valve 4 in the portion 2,air-pressure valves 5 and 6 in the member 1, an auxiliary air-pressurevalve 7 adjoining the portion 2. an operating handle 8, pivoted to themember 1 by a pin 9, for controlling the valves 4 and 6, a latch member10, pivoted by a pin 11 to a standard "12 on the member 1, for

holding the handle 8 and connected by a link 13 to a member 14 that'ispivoted by a pin 15 to a standard 16 on the member 1, for controllingthe valve 5, a liquid inlet pipe 17 communicating with the portion 2, anair pressure pipe18 attached to the member 1 and communicating with thevalves 5, Sand 7. an adjustable spray-distributing member 19 ofparticularly novel design attached to the portion 2, a. rod 20, ofsubstantially L-shape,

extending through one end of the member 1 and to which it is adjustablysecured by a screw 21, a member 22 through which one end of the rod 20extends and is ad'ustably secured thereto by a screw 23 and a rod,

24, for mounting the sprayer on any-suitable supportin device '(notshown), that 'extends throug the member 22 'and is adjustably securedthereto by a screw 25.

As shown in Fig. 3, the sprayer is ada ted to be moved in the clockwisedirection, rom" its spraying position, about the axis of the through anangular displacement of substantially 90., This is to remove the sprayerfrom the path of passing objects to. be sprayed, such as automobiletires as set forth. in the above mentioned patent.

The-portion '2 is divided internally, as shown in Fig. 6, into two;chambers or re- .servoirs 26 and 27 by means. of a hollow plug 28 thatis inserted in" its upper end.

' is adapted Theupper reservoir 26 is connected, by means of a ipe orhose (notshown) that or. attachment to the pipe '47-,

witha "tank or other suitable spraying liquid sburce (not shown). Anaperture 29, in the bottom of the plug 28, pr0vides -comniunicationbetween the upper and lower reser voirs that is controlled bytheyalve 4.having a stem 30 that projects out of the top of the plug 28. The stem30,'having a ball or valve member 31 at its lowef end that registerswith "the aperture 29, is held in its uppermost position by a spring 32.The bottom of the reservoir 27 is closed by means of a remo vable screwplug 33.-

The nozzle 3 communicates with the reservoir 27 at a position adjacentthe top of the sage 34,;as shownin Figs. 4 and 6, with a pamage 35 inthe member 1- that leads to a relatively-small chamber 36 to "the valve"6. An aperture, in the bottom'of the chamber 36, is closed'by a ball orvalve member 37 that is normally held against its seat by a spring .38,the said valve controlling-emumunicatio1i between the chamberi36' and alower chamber that is connected, by ipe .or conduit 18 and another {hotshown) to zrsource ofcompipe or hose pressed air. I t I The ball 37 isoperated by mea ns of a stout or/rod .40 that projectsout of the top ofthe member 1, and isnormally held in its uppermost position by a sprin41. I Q

The chamber 39 is a so connected, by means of a passage 42,-with anotherchamber 43 containing a ball 44, of the valve 5, that controlscommunication between the chamber 39 and an upper chamber 45. The ball314: ormally retained against its seat b a spri P 46 and is at tuatedbye sham 7 that projects out of the top of t e member 1 C69 andnsheld inits uppgrmost position by a f ,-,a-pipe49,- with the.

spring 48. The cham er portion of the reservoir 27, the pipe-4 withrespect to the reservoin2 as to be above 96' the latter when the sprayeris moved about 73 having stems. By adjustmern; of. the screws 50 andscrew ,61 :and adjusted, "with respect to the nozzle 3, by themanipulation of the screw- .desired position; 7 F 1 Horizontal plates orportions 70 and 71,

r is connected, by

in so positionedt the rod 24 to its inactive position to, thereby,

prevent any of the spraying liquid from flowingthereinto.

The valve stems 30 and 40 are actuatedto '0 en the valves 4: andv 6 andto, thereby, 70

adm1t both the liquid or mixture to be 1 sprayed and air to the nozzle3, by means of the handle 8 that carries screws and 51 adapted 'to,engage the tops of the valve 51, the valves may be caused to open-t0the proper degree, and in the proper relation to eachother, whit-hisreferably simultaneous.

The handle 8 is a so' providedwith a pin 52 that is loosely mounted inslots 53 o a bracket 54 on the handle and is adapted o engage the member'10 that has a lateral projection 55 in which is threaded a s'crew 56for engagment with the top, of the valve s em 47; The member 10 has ashoulder 57 for the rece tion of the pin 52' when "the handle 8 isepressed. i v I A y'0ke 58 at the top of the member 14 extends to aptisi ion over a collar 59 disposed adjacent the 'u per end of the stem40.:

The ad'usta 1e distributing member 19 is remova ly andadjustablymounted, by screws 60 and 61,,to two standards 62 and 63," respectively,securedto the ortion'2. The screw"61 extends through aside slot 64 in avertical arm 65 of the member 1-9 and rigidly secures the latter to. aportion 66 that is pivoted by a-pin 67 to the, standard The screw "60Lis provided with an annular groove-68-for the reception \of the upperend of the arm 65, that has a vertical slot 69 therein. The member 1maybe, thereby, readily'removedby releasing the.

Hi5 That ispby turnlng the screw 60, the member 19 is' turned about atthlower end of the arm 65', are connected '110 by two" relatively-thinstream-line portions' 72 of knife edge extending in alignment with theaxis of the nozzle and a triangillar portion 73 disposed between,andconnectetb to," the. portions 72 and havingloneapex thereof on a'medianline efitending in thev x direction of theaxis of the nozzle 3. g

. By suitably adjusting the member 19, the

lportionsl72 ahd 73. may be' placed in such!' relation with ixe'spct tothe nozzle 3 as to distribute the spraying fluid over one of a pluralityof selectively predetermined areas. f The portions 72 being extremelythin and having sharp edges, ofler substantially no. opposition. to theforward distribution of a portion of the fluid. .-The portion '73 isshaped to deflect a'portion of the sprayla'terall at an angle with theaxis'of the nozzle, t e arrangement of the ortions 72 and been found todistributethespraythe pin 67to'any l ing fluid uniformly over arelatively-wide area close to the nozzle and to substantially eliminatethe rebound mist or dripping nor mally attending the placing ofanobject'in the path of a rapidly flowing spray stream.

The stream-line and-knife-edge members 72[. further do not split thespraying fluid as.

' of the slots 53, itwi-l-l engage the member andv be thus moved to theother end of the slots 53, this movement of the pin permitting it tomove to its position under the shoulder 57 withoutmoving the latchmemher 10 to aetuattf the stem 47. The depression of the handle 8, atthe samefltime, actuates the stems 30 and 40 to thus open the.

valves 4 and 6 to admit both liquid and air to the nozzle 3. The air isadmitted through sition, during which the chambers 39 and 36,the'passage and the annular passage 34. The pin 52, cooperating with theshoulder 5'? in the mem ber 10,' holds the handle 8 in depressed-potimethe spraying op- .eration occurs.

To stopthe spraying operation, the latch member 10 is moved to'the left,as shown in Fig. 3, thereby permitting the-handle E1 35 to be raised bythe spring 32'and the valve 4 to be closed, to cut off the flow ofliquid to the chamber 27. Movement of the member 10, to release thehandle 8, causes the valve 5 to be'opened and, by reasomofthe connectionof the member 10 through the link 13 to' the member 14, permits thevalve 6 to be retained momentarily in its open po? .sition, .with theresult that air is force d through the spraying fluid passage 27 and,

consequently, through both the liquid and through complished by' reasonof air being forced be opened to force air through the pipe 74 ,into theupper chamber 26.

The sprayer is thus efi'ectively cleaned at the completlon of thespraying operation and freedom from clogging and great reliability ofoperation are thereby insured.

clud1ng valvegforsupplying a. plurality of" The valve 7 is providedto'periodically force air through the upper reservoir 26 and the pipe 17to remove encrustation there- *from and insure a free flow of sprayingfluid atall times. L I )7 In the modification of the spray-distributeing'member 19, shown in Figs. .8, 9" and 1O,

the parts are substantially the same as 'in the above described formwith the excep tion'ot an intermediate't rirn lar portion" 7 which iscut away to 'pi'ovidg controls communication between the 1'eseran?passages of the nozzle This is acthe pipes 49. The valve 7 may alsoracemes. '77,

and 78 at itsupper and lower sides on opposite sides,'res spray stream.ertically-aligned edges 79, Fig. 9, of the cut-away portions of theportion 7 6 serve substantially the same'purpose as the knife-edgedportions 72 of the above described form of distributor and cut ectively,of the axis of the the spray stream to distribute parts of it to oneside and to permit parts of it to flow uninterrupted.

' Inthe modification of the spray-distributing member 19, shown in Figs.11,12 and 13, an intermediate spray-distributing portion 80, between theplates70' and 71, is secured in fiat abutting engagement with the upperplate 70 and spaced from the lmwer plate 71 by pins 81.

The 'modific-ation of the spray-distr bute ing-member 19, shown in Figs.M and 15,

comprises a single integral member 82 having the vertical slotted arm65, as in the ot er forms, and a lower portion 83 bent at an angle withthe arm 65 and shaped to distribute the pray uniformly over apredetermined area. Q a

Any of the forms of the member 19, when in position on the sprayer, maybe adjusted by manipulation of the screw :60 to vary the direction andscope of." the spray with respect to an object to be sprayed to therebyinclude areas of selectively-predetermined forms and dimensions. \V1ththe member 19 as shown 1n Figs-l and 5, an even and fluid may beobtained which, since it has no ,uniform stream of any type ot'sprayingheart as in the ordinary type of spray, is

particularly adaptable for spraying rubber,

paint, varnish, etc.
